These investigations also illuminate the robustness of parameterized
theory-agnostic inspiral tests in general, which is more
straightforward in an approach like FTI that strives to expose all
flexibility (or arbitrariness) of the test. Comparing this to the
TIGER infrastructure [1]}, [2]}, we
note that TIGER is designed and implemented within a
particular family of waveform models, with a specific prescription for
the transition to the merger-ringdown phase being essentially
inherited from the underlying GR waveform.
